Connecting a external alarm which requires wired trigger with SmartHub

I want to use as an external alarm system , based on automated alarm raised from smart hub or manually through hub.

As far as i can understand, this alarm system require a wired trigger signal. is it something possible to achieve via smartthings? like attaching some smart toggel or something?

Quite new to smart home automation, so any directions would be highly appreciated :slight_smile:

Just an open/close relay.

some open/close relays have accessible screw terminals, that are basically just contact closures, they can be set to normally open or normally closed, and can be used to supply the dry contacts for wired triggers. You just need to find one you like with the accessible terminals.
